Problems faced by traditional edge device management in access network devices

There are many things worth learning about connecting network devices. Here we mainly introduce the problems faced by traditional edge device management in accessing network devices. In the modern telecom operation field, network access equipment is the most important part of network facilities. The quality of network operation is directly related to the vital interests of operators and network users. Only by ensuring the uninterrupted normal operation of the network can the interests of both operators and network users be guaranteed. However, due to factors such as the driving force of the technology market, access to network devices has long been a blind spot in remote network management.

Main problems faced by traditional edge device management

This year, the transition from a transmission network to a business network has gradually become a trend. E1 leased line service has become an important technology for Private Network Construction with its advantages of high reliability and high quality assurance. However, in the process of service-oriented transmission networks, the lack of management of traditional PDH Optical terminals and other edge devices seriously affects the provision of services. We all know that PDH has always been in a very embarrassing position in the transmission network application field.

On the one hand, SDH networks do not provide protocol standards at a rate of 2 m, and the access to optical network services is still largely dependent on traditional PDH Optical terminal machines. On the other hand, PDH lags far behind core networks in terms of protocol interconnectivity and OAM features. This conflict exists in the era when the transmission network is the underlying bearer network. Once the transmission network achieves role conversion, it becomes a basic business network platform, the blind zone of business access will greatly hinder the promotion of business. Therefore, in recent years, providers of various access devices have been devoted to R & D of network device management systems, trying to change the blind spots of network devices in the access network, this allows various network edge devices to be integrated into a unified network management platform, helping operators and private network users achieve full network monitoring and management.

Requirement Analysis of access network device management

There are big differences between the environment of connected network devices and the core network environment, and there are some differences in the requirements of the network management system. From the operational perspective, the current network management system of edge access devices must meet the following requirements:

Practical

The functions of the network management system should be based on the user's actual needs for network operation and maintenance, and should be closely integrated with the actual network conditions and specific management work. The use of the network management system should be able to reduce operation and maintenance costs, improve service quality, and increase economic benefits.

High Efficiency

It can promptly and effectively discover and locate network operation faults to save network operation and maintenance costs and improve network operation quality. Scalable. Network management content and management methods are changing and evolving. Therefore, the construction of the network management system is sustained and long-term. The construction of network management should pay attention to scalability, the network management system can still be applied when the network scale is expanded, the network service is increased, and the network management is changed. Friendly man-machine interface. Because network users and network operators differ greatly in technical expertise, in the management environment of access networks, network users urgently need to manage and maintain their networks, therefore, a user-friendly graphical user interface GUI enables network users to quickly master network management and maintenance skills.

Development Direction of Access Network Management Solution

A modern network management solution should be cost-effective, practical, and centrally managed by multiple devices. With friendly man-machine interfaces and menus, administrators can understand and master the running status of devices in real time, view network devices at any time, and handle faults. Through the database management system, you can collect statistics, summarize, and analyze the alarm information, status information, and performance information of each device, and perform centralized device monitoring for equipment maintenance personnel in real time to find the cause of the fault as soon as possible, it provides advanced measures to ensure normal network operation and improve work efficiency. The current access network management system is usually composed of a network management card, a cascade card, a NMS server, and a database system. It has the following features:

Security

The system can use the user management module to add, delete, modify user information, and set hierarchical permissions. The Network Management card also provides the password management function to ensure high security of the system. Scalability. You can smoothly upgrade the network management system by using the Network Management Card and cascade card provided by the system, which is scalable. Standardization. The Network Management Card can convert the information reported by cards at all levels into standard SNMP Packets and summarize the packets to the NMS server through the TCP/IP network. At the same time, it can also be integrated into the integrated network management system of other manufacturers, with the characteristics of standardization.

Practical

The system is tailored to the user's application environment and has basic configuration management, fault management, performance management, security management, data information management, and other functions. It has practical features. Friendly man-machine interface. The system uses graphical user interfaces and powerful menu functions to allow users to quickly and intuitively learn operation details.
